Taking this picture of the moon exposed for ~1/25 of a second at prime focus of an f/8.3 120-mm refracting telescope, I tested for the first time a custom-made remote manual shutter used to avoid camera shake and telescope vibrations created by the release of the built-in camera shutter. Unsharp mask was additionally used. Also, strong libration (9.41°) is visible on the trailing limb as we can see much further east of Mare Crisium than we usually do.
